I am really interested to learn networking subsytem in Linux kernel. So I am trying to start with the kernel build in Fedora 15. I followed the tutorial available at http://fedoraproject.org/wiki/Building_a_custom_kernel
Kernel build really took long time but wat I found out was 4 versions of same kernel is getting build at the end eventhough if I select DEBUG_ONLY option
Is there any way I can speedup up the kernel build by just building the required version ?
Can anyone tell me the practical way to understand linux network internals via code go through ? I am at present just concentrating more on Ethernet and IP flow .. not much interested with legacy networks or others.
